The genera Acruliopsis Zerche and genus Xylodromus Heer contain four species and 13 species worldwide, respectively. In East Asia, all species of Acruliopsis are distributed and two of Xylodromus are described, which are new to the Korean Peninsula. Little is known about the habitat of Acruliopsis species, but our specimens were collected under bark of log or by flight intercept trap. The Xylodromus species is found in leaf litter of forest, in nests of the mammals or birds, or sometimes in granary. In this paper, we report Acruliopsis ussuriensis Zerche and Xylodromus daimio (Sharp) for the first time in the Korean fauna. We provide the habitus photographs, illustrations of diagnostic features and a key to the genera of the tribe Omaliini MacLeay in Korea.
